for domestic water preparation
Domestic water preparation is confi gured with the aid of SERVice parameter 31.
Additional information on the control models and the most important applications
can be found in chapter 8.2.
Effect of binary / pulse input (terminals 21, 22)
If the external switching contact is closed, this SERVice parameter can be set
appropriately (SP07 = 0, 1 or 2) to infl uence the heating programme, as long as
the controller is in automatic mode. If the contact is opened again, the controller
will operate according to the weekly / calendar switching programme again and
the following apply:
1 = HK in back-up mode if contact is closed •
2 = HK in reduced mode if contact is closed •
3 = HK in nominal mode if contact is closed •
Alternatively, the input can be used for quantity metering (and therefore for
quantity limitation as well), to limit see page or to forward a fault signal (using
a modem via SMS or via the confi gurable relay output to another device). For
SP07, the values mean:
4 = input used as pulse input for quantity metering •
5 = input used to limit seepage •
The minimum fl ow can be limited. A signal from the auxiliary contacts of a •
control unit can be used to do this. If the contact input is closed, the valve on
the primary side closes and is not opened again until the setpoint for the fl ow
temperature is 5K higher than the actual value.
6 = input is a fault signal input, used to forward fault signals from other devices •
